Many studies have suggested a correlation between the C677T mutation in the methylenetetrahydrofolate reductase (MTHFR) gene and diabetic nephropathy (DN), but their results are inconclusive.
To confirm this correlation, we performed a meta-analysis of 15 studies. The dichotomous data are presented as odds ratios (OR) with 95% confidence intervals (CI).
The results of this study suggested that the MTHFR 677 T allele was more likely to increase the risk of DN in Asian (OR = 1.466, 95% CI = 1.143-1.880, P = 0.003), West Asian (OR = 1.750, 95% CI = 1.150-2.664, P = 0.009), and Chinese populations (OR = 2.162, 95% CI = 1.719-2.719, P = 0.001), but not in East Asian or Japanese populations. The carriers of the MTHFR 677 T allele were associated with progression of DN in the "5-10 year duration" group, but not in the "> 10 year duration" group (OR = 2.187, 95% CI = 1.787-2.677, P = 0.001).
Development of DN is associated with MTHFR C677T polymorphisms in Asian populations, especially in early type 2 diabetes.
许多研究表明亚甲基四氢叶酸还原酶(MTHFR)基因的C677T突变与糖尿病肾病(DN)之间存在关联,但结果尚无定论。
为证实这种关联,我们对15项研究进行了荟萃分析。二分数据以比值比(OR)及95%置信区间(CI)表示。
本研究结果表明,MTHFR 677 T等位基因更有可能增加亚洲人群(OR = 1.466,95% CI = 1.143 - 1.880,P = 0.003)、西亚人群(OR = 1.750,95% CI = 1.150 - 2.664,P = 0.009)和中国人群(OR = 2.162,95% CI = 1.719 - 2.719,P = 0.001)患DN的风险,但在东亚或日本人群中并非如此。MTHFR 677 T等位基因携带者在“病程5 - 10年”组中与DN进展相关,但在“病程> 10年”组中并非如此(OR = 2.187,95% CI = 1.787 - 2.677,P = 0.001)。
在亚洲人群中,尤其是在早期2型糖尿病患者中,DN的发生与MTHFR C677T基因多态性有关。
